Hey Tindo,
They really won't do unless you have a cool viv. They can handle it down to around 36F-38F. I have mine outside. Of course with our nights dipping into the high 30s the past couple of days I sit them on my outside window ledge just in case. Don't want to lose them. They like their feet moist but their tops dry. They grow in cloud forests in Indonesia. There are only 2 retailers I know of. One is in your region and one in CA.
1. White Oak Orchids in California

I recommend driving to Parkside to buy if possible-check with them.
